The Mathews stability graph method was presented for the first time in 1980. This developed to assess of open stopes different underground conditions, and it has an impact on evaluating safety excavations. With development technology growing experience applying computer sciences various research disciplines, mining engineering could significantly benefit by using Machine Learning. Applying thos...

The main objective of this article is to provide a general numerical approach for the hydro-mechanical (HM) modelling tunnels excavated in saturated rock masses exhibiting plastic behaviour, considering multi-stage excavation process. First, new method has been proposed and implemented software CODE_BRIGHT, based on finite element method. In method, stresses elements are reduced smoothly. As ve...

T he origin of our own genus remains frustratingly unclear. Although many of my colleagues are agreed regarding the “what” with respect to Homo, there is no consensus as to the “how” and “when” questions. Until relatively recently, most paleoanthropologists (including the writer) assumed Africa was the answer to the “where” question, but in a little more than a decade discoveries at two sites b...
